Description

one

This invention relates to the mechanization of loading and unloading operations.

Known lifting devices for lifting and cleaning the hatch covers of gondola cars, containing a traverse with suspended electromagnets attached to it, lowered into an empty car to close the hatch covers.

The purpose of the invention is to mechanize the cleaning process of hatch covers of gondola cars before they are lifted. For this purpose, at the ends of electromagnets, made annular with grooves, the crosses with blades and winches mounted in a vertical plane are mounted on drive shafts passing through central holes in the poles of electromagnets. In such a device, the traverse can be made of three sariirno interconnected links.

FIG. 1, 2 and 3 shows the proposed device. It contains a yoke /, made of three links pivotally interconnected with armatures 2 pivotally suspended from them, having annular ends 3 with grooves 4. In the central hole of the electromagnet pole a drive shaft 5 is attached to the lower end of which the crossbar 6 is movable in the vertical plane with blades mi 7 and brushes 8.

After unloading bulk cargo through the hatches, the load-lifting device is lowered into the gondola 5 above the first pair of open hatches until it contacts the cover plates 10. At the same time

the side links of the crosshead change the angle of inclination and the hingedly suspended electromagnets are pressed by the brushes to the inclined covers 10. Then the crosses begin to rotate, which by means of brushes and blades

clean the covers.

After cleaning, the electromagnets are turned on and the lifting device is raised. In this case, the electromagnets raise the covers and press them to the gondola bodywork. Further

electromagnets are disconnected and a lifting device is installed above the next pair of open hatches.

Claims (2)

1- A lifting device for lifting and cleaning the hatch covers of gondola cars, containing a traverse with twin electromagnets attached to it, lowered into an empty car to close the hatch covers, characterized in that, in order to mechanize the process of cleaning the covers before they are lifted, at the ends of the electromagnets, crosses mounted in a vertical plane with blades and brushes are mounted on drive shafts passing through the central holes of the electromagnets, the lower parts of the outer poles of which are annular with grooves. 2. A device according to claim 1, characterized in that the traverse is made of three links articulated among themselves.
